SHINGLE-DIE.

SPECIFICATION forming part of Letters PatentNo, 767,913, dated August 16, 1904.

Application filed July 16, 1902. Serial No. 115,873. (No model.)

To all whmn it may concern:

Be it known that I, NOAH ELDRIDGE PALMER, a citizen of the United States of America, and a resident of Lake, in the county of Spencer, Indiana, have invented a new and useful Improvement in Shingle-Dies, of which the following is a specification.

This improvement is additional to the joint invention of myself and Richard C. Downs, set forth in our specification forming part of Letters Patent No. 685,294, dated the 29th of October, 1901. In common with the die set forth in said previous specification the present die is intended and adapted for the production of what are known as clay shingles, and the provision of the same in the die with end flanges or hooks integral with the body of the shingle, the flanged shingles being cut transversely from the strip of clay as it issues from the die.

The objects of the present invention are to provide for simultaneously producing two of the flanged shingle-strips, and thereby red ucing the resistance at the outlet of the mill, so as to prevent heating the clay in its passage through the die, to equalize the feed of the clay at the respective edges of each flanged strip, to provide for removing stones and like obstructions from within the die without detaching the die as a whole, and to provide for strengthening the flanged ends of the shingles.

The invention consists in certain novel features of construction and combinations of parts hereinafter set forth and claimed.

A sheet of drawings accompanies this specification as part thereof.

Referring to the drawings, Figure 1 is a face view of the improved die. Figs. 2 and 3 are respectively top and side views projected from Fig. 1. Fig. 4 is a section on the line A B, Fig. I. Fig. 5 is a perspective view of a perspective view of the product of the improved die.

Like numbers and letters refer to like parts in all the figures.

Apart from said clearing-iron,Fig. 5,(shown at lin Figs. 1, 3, and 4,) and a pair of bolts 2, by

which said clearing-iron is normally fastened in place, as 1n the figures last named, the iml proved die is preferably and conveniently a single casting, of suitable iron or steel, such casting constituting what is hereinafter termed the body of the die, comprisinga back plate 3, provided with bolt-holes a, Fig. 1,for attach- V ing the die to the die end of a horizontal claymill, concentrically with the customary mixing and feeding screw. As in said previous die, the body said attaching back plate, and is provided with a forwardly-extending wedge-shaped chamber b of substantially the entire width of the die in a central horizontal plane, which is the plane of said clearing-iron.

Above and below the clearing-iron 1 two horizontal outlet-openings c and (Z are formed, one above the other, ina pair of lips 4 and 5. Said clearing-iron 1 forms a partition between the two outlet-openings, and the inner edge of the clearing-iron is sharpened, as in Figs. 4 and 5, to divide the clay and distribute it to the respective outlets.

The flange-forming grooves 6 and 7 of the respective outlet-openings are formed at opposite sides of the die and extend respectively upwardly and downwardly so as to equalize the feed of the clay at the respective lateral edges of the shingle-strip, and the front 6 of the die is bellied, as in Fig. 2, to equalize the feed between said lateral edges.

Inward projections 8 and 9, integral with the respective lips 4 and 5, project into the respective outlet-openings 0 and (Z, as in Fig. 1, to bevel the outer angles f of the shingles, Fig. 6, at their flanged or hooked ends by compressing the clay at these points, and thus to strengthen their hooks 9, Fig. 6.

The body of the die may be composed of two or more castings bolted together, if preferred, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention. and desire to patent under this specification- 1. A shingle-die having a pair of horizontal lips in front, each providedwith an outlet-opening extending in the direction of the feed, and a removable clearing-iron forming a partition between the two outlet-openings.

2. A shingle-die having a pair of horizontal portion projects forwardly from lips in front, each provided with a horizontal outlet-opening extending in the direction of the feed, a removable clearing-iron forming a partition between the two outlet-openings, and vertical fastening-bolts extend ing through said lips and said iron at the respective ends ofthe latter.

3. A shingle-die having a pair of'horizontal lips in front,each provided with an outlet-opening having a flange-forming groove extending in the direction of the feed at one side of the die, and a removable clearing-iron forming a partition between the two outlet-openings.

4. A shingle-die having a pair of horizontal lips in front, each provided with an outlet-opening having a flange-forming groove extending in the direction of the feed at one side of the die, and a removable clearing-iron forming a partition between the two outlet-openings and having a sharpened inner edge to divide the clay and distribute it to the respective outlets.

5. A shingle-die having horizontal outletopenings in front, each provided with a flangeforming groove extending in the direction of the feed at one side of the die, and constructed with inward projections adapted to compress and bevel the outer angles of the flanged edges of the strips of clay as they issue from the die, substantially as hereinbefore specified.
